| 目的 探讨含氮硼酸脂的摩擦学性能及轧制润滑性能。方法 合成一种新型含氮硼酸酯挤压抗磨添加剂（NB）。将合成的含氮硼酸酯分别和磷酸三甲苯酯、磷酸三丁酯进行复配后加入铝材轧制基础油中，配制成多种铝材轧制润滑油。利用四球摩擦磨损试验机考察多种铝材轧制润滑油摩擦学性能，利用轧制实验考察其轧制润滑性能，利用扫描电子显微镜观察轧后表面形貌。对多组样品的磨斑直径、摩擦系数、最大无卡咬负荷、轧制压力、轧制摩擦系数、最小可轧厚度和轧后表面质量进行对比，探究含氮硼酸酯复配比例对铝材轧制润滑油摩擦学性能和轧制润滑性能的影响。结果 当含氮硼酸酯和磷酸三甲苯酯、磷酸三丁酯的复配系数为0.5和0.25时，样品的摩擦系数分别降低了35.2%和18.4%，磨斑直径分别降低了48.4%和19%，表现出比单体添加剂更好的抗磨减摩效果。轧制实验也表明，添加含氮硼酸酯后，实验轧制压力降低到了 164 MPa 和160 MPa，轧制摩擦系数降低到了 0.076 和0.078，最小可轧厚度分别减少了 23%和21%。轧后铝板表面平整，犁沟深浅均一，表面质量好。结论 铝材轧制基础油中加入含氮硼酸酯后，改善了摩擦学性能和轧制润滑性能。含氮硼酸酯分别与磷酸三甲苯酯、磷酸三丁酯复配后具有良好的协同效应，轧件表面质量好。 |

| The work aims to study tribological properties and rolling lubrication performance of nitrogen-containing borate ester. A new extreme pressure anti-wear additive of nitrogen-containing borate ester (NB) was synthesized. The synthesized nitrogen-containing borate ester was firstly mixed with tributhyl phosphate, tricresyl phosphate, respectively. Then the mixture was added to aluminum rolling base oils in proper proportion, and finally aluminum rolling lubricating oil was prepared. Tribology properties of various lubricating oils for aluminum rolling were investigated by a four-ball friction-wear tester. Rolling lubrication performance was analysed by performing rolling experiment, rolled surface morphology was observed by scanning electron microscope. By comparing wear scar diameter, friction coefficient, maximum non-seizure load, rolling pressure, friction coefficient of rolling, minimum rolling thickness and rolled surface quality, the influences of mixing proportion of nitrogen-containing borate ester on tribological properties and rolling lubrication performance were investigated. When the mixing coefficient of nitrogen-containing borate ester to tributhyl phosphate, tricresyl phosphate was 0.5 and 0.25, respectively; friction coefficient of the sample decreased by 35.2% and 18.4%, respectively; and wear scar diameter decreased by 48.4% and 19%, respectively, which showed better anti-wear and anti-friction effects than monomer additives. The rolling pressure reduced to 164 MPa and 160 MPa, respectively; the friction coefficient of rolling reduced to 0.076 and 0.078, respectively; and the minimum rolling thickness decreased by 23% and 21%, respectively. Rolled surface was smooth and of good quality with uniform furrows. Tribological properties and rolling lubrication performance are improved by nitrogen-containing borate ester, mixture of the two has good synergistic effect, and rolled pieces are of good surface quality. |
